CHICAGO — Michal Handzus is every day of 37 years old and 15 seasons in the NHL. He knows he’s near the end of his career. He knows he’s slower than most of his Chicago teammates.

He also knows how to finish a play in a big spot.

Handzus scored at 2:04 of the second overtime, and the Blackhawks beat the Los Angeles Kings 5-4 in Game 5 on Wednesday night to stay alive in the Western Conference finals.

Brandon Saad made a nice pass to the middle, and the oldest player on the ice beat goaltender Jonathan Quick with a backhander for his second goal of the playoffs. The Slovak center celebrated by pounding the boards behind the net as the sellout crowd of 21,871 roared.

“Saad, two guys went on him and I got open,” Handzus said. “I was surprised I got open like that, but he waited and waited and gave me a great pass.”

Handzus has been all over Chicago’s lines all season long as the Blackhawks searched for a second-line center behind captain Jonathan Toews. His biggest value right now is on the penalty kill, but it was his offense that kept alive Chicago’s title defense.

“I want to help the team as much as I can,” Handzus said. “I’m playing on the PK a lot. I’m not playing very well offensively. I’m glad I came through.”

Saad had a goal and two assists to help Chicago stop a three-game losing streak. Brent Seabrook, Johnny Oduya and Ben Smith also scored, and Patrick Kane set a playoff career high with four assists.

“Personally, I thought Saader was the best player on the ice tonight,” Kane said. “He was bringing so much speed and puck protection.”

Game 6 is Friday night in Los Angeles.

Back at home for Game 5 after a disastrous stay in Los Angeles, the Blackhawks put together a terrific start. But the Kings weathered the storm and then stepped up their attack in the last part of the first period.

“We go home and we come out with a better effort,” Kings defenseman Jake Muzzin said. “We’ve got some experience and veterans in here who know what it takes to stop it.”

Former Ranger Marian Gaborik and Dustin Brown each had a goal and an assist, and Jarret Stoll and Tanner Pearson also scored for the Kings, who led 4-3 after two periods. It was Gaborik’s NHL-best 11th playoff goal.

Quick and Chicago’s Corey Crawford each stopped 40 shots.

Los Angeles was in position to advance to its second Stanley Cup final in three years before Smith drove to the net and swept in a rebound 1:17 into the third. Smith’s third goal of the playoffs set the stage for a frantic finish as both sides pushed for the winning score.

“It’s not easy,” Kings forward Justin Williams said. “Attaining your ultimate goal is never easy and we’re going to do our best to get it done.”
